On-loan Chelsea forward Michy Batshuayi came off the bench to score an injury-time winner as Borussia Dortmund beat Eintracht Frankfurt.

Peter Stoger admits he left Michy Batshuayi on the bench to ease the workload on the Belgian striker, whose brace lifted Dortmund over Eintracht Frankfurt.

Marco Reus hopes Borussia Dortmund can sign Michy Batshuayi on a permanent contract when his loan spell finishes at the end of the season.

The Chelsea striker has been crucial for Dortmund since January, with an upturn in form giving them a three-point cushion in the Bundesliga’s Champions League places.

After announcing himself with five goals in three matches, Batshuayi went without a goal in five games. But after coming off the bench against Eintracht Frankfurt on Sunday, he scored twice in the closing minutes — including the last-gasp winner in a 3-2 victory.

“I’d be very pleased if Michy were to stay,” Reus told reporters following a crucial win against rivals for a place in Champions League. “He’s shown how important he can be for us.”

Michy Batshuayi was again Boruddis Dortmund’s hero against Eintracht Frankfurt.

Dortmund sporting director Michael Zorc did not go into details about the chances of signing Batshuayi to a permanent deal when speaking to Bild.

“It’s clear that we will have a good setup for this position next season,” he said, deflecting a question about Batshuayi’s future.

Bild also claimed that Dortmund would have to invest at least €60 million to secure the Belgian’s service beyond the summer.
